I'm assuming that your '89 Chevy has the C6 compressor, which utilizes teflon sleeves for the internal pistons. The teflon sleeves wear out, and the small pistons slap inside their chambers, making a sound like marbles in a can. Eventually, the compressor will seize.

They're fairly expensive compressors, so brace yourself!

SOURCE: transfer case making roaring rattling sound

it's possible you might need to just change the trans case fluid.... it's a pretty simple task, i usually do all the small minor work first before i take it to a dealer to fix.... if they said you need a new trans case, but didn't tell you why, more than likely there might be something you could do yourself to make it better... those service men have been working around vehicles long enough, they should be able to tell you exactly what's wrong!
i would also do a tranny fluid change to... some of the noise could be coming from there too -- when you change either fluid, add a little lucas transmission fluid stabilizer, it helps alot with seals and makes the fluid stick to the gears better...

SOURCE: Front End Noise, Chev Cavalier

It sounds like you have a bad c v or constant velocity joint. Look under the car next to the wheel look for a rubber accordian type unit, if the rubber is torn or lose the grease has escaped and damaged the joint. You can replace it yourself, but if your not mechanically inclined would say take it to a shop.

SOURCE: front end rattle

It's a loose steering column. Remove the black plastic shield under the steering wheel. Lossen the bolt that holds the two shafts together, slide them together as far as they'll go, and re-tighten the bolt. It's that simple... to stop that annoying rattle.

SOURCE: rattling noise

Try the cupholder on the drivers side. Then, if it's like the issue I had, push the plastic around the dimmerswitch wheel in toward the rest of the dashboard. THAT'S where the rattle was for my car. Also a 40mph and above issue. If that doesn't do it, try putting pressure on different parts of the dash to eliminate the fitting together of the molded plastic as the issue. Other then that, I'd have to be there to see what it could be!

My 2004 Prius has a rattling metallic sound on acceleration. It is coming from the top of the engine on the passenger side. Does anyone know what this can be?


Does the car make this sound when the car has just been turned off and engine is still hot? Lightly push the car back and forth while it's in park. Does it still make that sound?

Loud rattle noise started on cold start up but goes away.Now makes noise on/off throttle all the time.Sounds like cat internals or heat shield,inlaws have same car,same noise


Sounds like the Cat could be bad. Get under the vehicle and hit the cat with your hand. If it rattles then you know what your problem is, if it doesnt rattle then start check the belts and tensioners

Making a rattling noise when i step on the gas.


several things could be wrong are you using 91 octane fuel or less? also it might be a timing issue you might be too far advanced in timing ... this causes preignition.. causing a rattle also cheaper fuel will do the same effect.. thanks Jerry holler if you need more.. also was the noise loud or just a mild noise ??
